One of my friends asked me this question, and I tried to explain it in a way anyone could understand. In thermodynamics, enthalpy is a...

Properly designing ventilation and air conditioning for a swimming pool is not a simple task. There are at least several dozen different...

At first glance, the answer to this question seems relatively simple. After all, there are many programs on the market for selecting...

If we have multiple sources of noise and want to determine their combined level, we cannot simply add them linearly because we are adding...

It may sound controversial, but I assure you that it concerns a serious engineering issue :) OPTIMIZATION OF VENTILATION UNIT PARAMETERS...

Having the privilege to participate in international projects, apart from obvious language barriers, there have always been technical...

Noise is an extremely important topic that many people struggle with. It's no wonder, as there is a certain apparent "mess" in acoustic...

You are probably wondering what I mean, and I don't blame you with such a title :). So let me ask you a question - if we design a...

I am often asked by people who are designing or renovating their homes whether a ground heat exchanger (GHE) is cost-effective. It is a...

Due to being the author of the IX CHART program, which is used by a considerable number of designers and others, I often receive various...

A very interesting topic that will interest anyone who is interested in eco-friendly solutions. What is adiabatic cooling? Simply put, it...

As promised, we continue the topic of adiabatic cooling in terms of investment and operating costs. In the last post, I showed that...

Many investors, when deciding on a ventilation system and type of heat recovery unit, wonder how much it will cost to operate the system...

Air dehumidification can be achieved through either condensation or adsorption processes. In full air conditioning processes,...

So what's the deal with humidification? Generally, there are two ways to humidify - with steam and with treated water. Which one is more...

What really affects the energy efficiency of a ventilation system? Does energy consumption depend solely on the efficiency of heat...

Sizing a ventilation unit is not a simple task due to the multitude of air parameters, but its selection largely determines the...

The article presents in a simple and clear way how to read basic transformations on the Mollier/Psychrometric chart.

A gust of horror blew by, but there are some indications for that, and as the Romans used to say, "Dura lex, sed lex". When I write about...
